Enhancing Video Streaming Delivery over Wired/Wireless Networks

Delivering streaming video over wired/wireless networks is challenging, since link errors commonly compromise throughput performance, smoothness, and eventually impair the perceptual video quality. We combine an efficient Additive Increase Multiplicative Decrease (AIMD) transport protocol with an end-to-end mechanism that effectively decouples wireless from congestion loss to abolish the damage of error-induced multiplicative decrease on flow throughput and smoothness. Based on simulation results, we show that our combined approach provides the desired functionality to bind operationally wired and wireless links, within the framework of bandwidth efficiency, smoothness and fairness. The proposed mechanism can be easily adapted and incorporated into existing AIMD protocols, allowing them to utilize more efficiently wireless resources.
